Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed November 22, 1913. Serial No. 802,415.

To all whom it may concern;

, Be it known that I, JOSEPH MIDGLEY, a subject of the King of Great Britain, residing at Washington, in the county of Kent and State of Rhode Island, have invented certain new and useful Improvements in Bunch-Preventer's, of which the following is a specification, reference being had therein to the accompanying drawing.

In combing and other similar machines now generally in use, trouble is experienced from the collection, in bunches or other form, of dust or short-staple fiber, from the material being treated, under the bearings of therolls, in the spaces between the bearings, and on the rolls between the ends of the leather or other fabric covering and the journals. Accumulations of this kind increase the resistance of the rolls to rotation, and from time to time. they. are drawn into the good material passing from the ma-.

chine and become incorporated with the material in such manner that it is impracticable toremove it, withtheresult that uneven yarns are produced, and the value of the output otherwise lessened. The device. provided by this invention is applicable to machines of the kind indicated now inuse, and it operates to prevent the fouling of roll-bearings and the assimilation of fouling matter bymaterial passing through a machine with which it is associated.

When read in connection with the description herein, the details of the invention and itsmanner of use will be apparent from the accompanying drawing, forming part hereof, wherein an embodiment of the invention as applicable to a combing-machine is disclosed, for purposes of illustration.

While the invention is exemplified herein in a preferable form, it is to be understood that it is not the intention to be limited necessarily thereto in interpretation of the claims, as changes within the scope of the claims can be made without departing from the nature and spirit of the invention.-

Like reference-characters refer to corresponding parts inthe views 'of the drawing, of, which- Figure 1v is a side view of the device; Fig. '2}-is.aperspective view, looking at the" other side; Fig. 3 isan end, view; Fig. 4.;i's'a view of the device on a roll; Fig. 5 is a perspective view of a portion of a combing-machine showing the device in place; and Fig. 6 is a sectional view, on the line 66, Fig. 5.

Having more particular reference to the drawing, 7 designates the device provided by the invention. In the form shown, the device is made of strong sheet metal, of a suitable width to contact with certain parts, and bent or otherwise fabricated to present reversely-curved faces or surfaces adapted to lie against or cover those parts. The intermediate portion constitutes a holding and protecting part8, shaped to conform to and partially embrace a roll near its end beyond the part that is fluted or covered with leather or other fabric. Continuing from the intermediate part in .a reverse curve is an end portion. 9, shaped to conform to and lie against an adjacent roll. .The end portion 9 is extended to one side, whereby it is wider than the intermediate portion. A covering 10, of leather or other suitable fabric, is secured to both sides of portion 9. This covering extends on the convex side to or about to the concave side of the holding part 8, and it extends from the concave side of portion 9 over a part of the convex side of the holding part. The covering also extends above the part of the wider portion 9 that projects laterally beyond the holding part, and here the two flaps of the covering material are secured together, by cement or other means, whereby a single flap 11 is formed. The material of the device, in the end portion opposite to portion 9, is bent or otherwise disposed to form a part 12 extending ina diverse direction from portion 9, for the purpose of having the end of a weight or spring stirrup seat thereagainst and to contribute to retention of the stirrup in place.

A manner of associating the device with rolls is illustrated by several figures of the drawing, and particularly by Figs. 5 and 6, which show parts of a combing-machine having adjacent cooperating rolls.

Referring particularly to Figs. 5 and 6, the machine has a lower piecing-roll 13, which ordinarily is flu-ted and usually is formed on a longitudinal shaft common to all combing-heads and driven from the driveheadof'the machine atone end; an upper fluted piecinggro'll H; and an upper detaching roll 15. The roll 15 usually'is covered larger fabric-bearing part the end of a stirrup 16 rests, the flange and abutment op-.

erating to prevent displacement of the stirrup longitudinally of the roll.

I In machines of the class referred to, having rolls arranged substantially as described, fouling matter accumulates on the roll 15 between the end of its fabric covering, which usually does not extend entirely up to the termination of the larger portion of the roll at abutment 15 and that abutment, and thence at times it works toward the end of the roll and into the bearings. There also is a tendency of fouling matter to accumulate in the space between the three rolls at A, Fig. 6. For the purpose of preventing these accumulations of fouling matter and its sub- 'sequently being drawn into the output of the machine, the device is associated with the rolls as shown. That is, the holding part 8 of the device is placed on roll 15 between its flange 15 and abutment 15 and then the end of stirrup '16, instead of resting directly on the roll, rests on the part 8 and against the then upper part 12, Which latter operates to prevent displacement of the stirrup. The stirrup in turn operates to hold the device in place. The covering 10 on the concave side of the lower part 9 is held under the rotative influence of roll 15 and in a measure by the stirrup against the lower roll 13. The lower part 9 being wider than the intermediate or holding part, it extends laterally, and its covering, and particularly the flap 11 thereof, contacts with that part of thelarger portion of roll 15 at the end that is devoid of fabric covering. Thus it willbe seen that the gaps between and on the rolls are filled in by the device and accumulations in those places prevented. It will be understood, of course, that a similar de vice is associated in like manner with the rolls at their other ends. 1

Having thus'described my invention, what I claim as new, and desire to secure by Letters Patent, is
